Why not just work it out? It's a simple application of Pythagoras' theorem.

Let's say the width is "x". The height will therefore be x*9/16, since it's a 16:9 aspect ratio screen.

So, by Pythagoras's theorem:

x*x + (x*9/16)*(x*9/16) = 8.9*8.9

1.3164x*x = 79.21

x*x = 60.172

x = 7.76

So, the screen is 7.8" wide and 4.4" high.
